Splenic trauma (pseudoaneurysm)

Case contributed by Jeremy Jones
Diagnosis almost certain

Presentation

Fall from 10 feet. Landed on back. Injury to right wrist.

Patient Data

Age: 12 years
Gender: Female
x-ray

Normal chest radiograph.

Large region of splenic hypoattenutation in the cranial portion of the spleen. Normal enhancement anteriorly and inferiorly. At the junction between normal spleen and non-enhancing spleen, there is a region of dense contrast. This represents a contained vascular injury (as opposed to active splenic hemorrhage), a pseudoaneurysm.

Case Discussion

A triple-phase CT was performed at an external institution. Three phases are not required in the assessment of pediatric trauma. A split-bolus study will give you the same information and is essentially the same as the third phase of this study.

In this case, isolated splenic trauma with a splenic laceration and active hemorrhage with contrast concentration on the portal venous phase study.
